He decided to create a full - length animated movie. No one did that before and his brilliant idea changed the whole world.
He founded with his brother a corporation with annual profits of approximately 35 billion U.S. Dollar. He also created Disneyland and the Walt Disney World and continues to be one of the most popular attractions in the world where children and even adults have a lot of fun.
He helped several federal agencies throughout his career. He created training films for the US military, propaganda films urging Americans to pay their taxes, and multiple anti-Hitler shorts meant to boost US morale at home; with this help he left a legacy of helping the nation.
He also produced a series of educational films that were specifically designed to be used for academic purposes within different grade schools then included in the standard curriculum for many classrooms throughout America.

He started to encourage as many children as he could to appreciate the value of education and stay in school in order to have a better chance at fulfilling their dreams in the future.
By making a 1941 goodwill tour Disney helped the State Department improving relations with South America (featuring a specially made movie entitled Saludos Amigos), and later aided NASA by developing documentaries about the space program.
Other important legacy was the creation of three Oscars awards created specifically for him; one for creating Mickey Mouse, another recognizing his contribution of music in the field of animation, and a specially made prize honoring Snow White and the Seven Dwarves that
